It's not a tight fit, it just doesn't fit. "Fit" means the retention mechanism works right out of the box, but that's not the case with your bulbs. If I have to shave down the prongs on $130 turn signal bulbs, you guys did something critically wrong with the design.

If you guys created a version two of the bulbs where they slid into the same position the stock bulbs do, then they'd be perfect. But as is, you have a product that no one should install for risk of damaging a very expensive headlight unit.

Over 100 sets installed since they were introduced, 3 of which I have done myself. Only one set broken so far (yours).

Still, I will send the feedback to the factory on your behalf. Perhaps they can improve upon it. Thank you all for your constructive inputs.
